Hi my lo dibbled really bad, chewed his hands and had rosy cheeks all the time from about 4 months old and everyone said 'oh there must be a tooth apearing' !! Well one appeared the other day - just before he was 8 months!!!? The night before it appeared through the gum he had an awful night (he has always slept well) and he got a tempature. This was the first time he had ever seemed ill and I was relived when I saw the tooth so I knew what was wrong! The second one has started to appear now at the same time and they don't seem to be bothering him. For the odd times I think they hurt him I use teething granules.
You could be waiting a while - sorry! Or they might appear tomorrow!
